Astragaloside II is a natural isolated from Astragalus. IC50 value: Target: In vitro: In vivo: The developed and validated method has been successfully applied to the quantification and pharmacokinetic study of AST II in rats after intravenous and oral administration of AST II. The oral absolute bioavailability (F) of AST II was calculated to be 0.79 ± 0.16% with an elimination half-life (t1/2) value of 1.92 ± 0.30 h, suggesting its poor absorption and/or strong metabolism in vivo [1].

体外研究 (In Vitro)
Astragaloside IV (10, 20, 40 ng/mL) inhibits NSCLC cell growth, whereas low concentrations of astragaloside IV (1, 2.5, 5 ng/mL) has no obvious cytotoxicity on cell viability. Moreover, combined treatment with astragaloside IV significantly increases chemosensitivity to cisplatin in NSCLC cells. On the molecular level, astragaloside IV co-treatment significantly inhibits the mRNA and protein levels of B7-H3 in the presence of cisplatin[2]. Astragaloside IV inhibits the viability and invasive potential of MDA-MB-231 breast cancer cells, suppresses the activation of the mitogen activated protein kinase (MAPK) family members ERK1/2 and JNK, and downregulates matrix metalloproteases (MMP)-2 and -9[4].

体内研究 (In Vivo)
Astragaloside IV (10, 20 mg/kg, p.o.) exhibits a potent ability to prevent cognitive deficits induced by transient cerebral ischemia and reperfusion. Astragaloside IV (10 mg/kg) and Astragaloside IV (20 mg/kg) can significantly decrease the levels of these cytokines compared to the Model group. Astragaloside IV significantly inhibits the level of TLR4 and its downstream proteins, suggesting that both MyD88-dependent and -independent pathways play important roles in the anti-inflammatory effects of Astragaloside IV. Astragaloside IV attenuates NLRP3 and cleaved-caspase-1 expression, and reduces Iba1 protein expression[1]. In the mice model, the high-dose astragaloside IV group has a significant increase in the 48-hour survival rate [60% (9/15) vs 13.3% (2/15), P < 0.05], significant reductions in the serum ALT and AST levels (P < 0.01), and significant reductions in liver histopathological indices and the degree of apoptosis of hepatocytes (P < 0.01), as well as a significant reduction in the content of MDA in liver homogenate (P < 0.01) and a significant increase in the activity of SOD[3].

Kinase Assay [4]
Briefly, MDA-MB-231 cells treated as indicated or tumor tissues are harvested and lysed in Mg2+ lysis buffer containing 50 mM Tris (pH 7.5), 10 mM MgCl2, 0.5 M NaCl, and protease inhibitor cocktail. Equal amounts of lysates are incubated with PAK-PBD beads at 4°C for 1 h. PAK-PBD beads are pelleted by centrifugation and washed with ish buffer containing 25 mM Tris (pH 7.5), 30 mM MgCl2, 40 mM NaCl. Active Rac1 is detected by western blotting.

Cell Assay [2]
Cell viability is determined by CCK-8 assay. To be brief, cultured NSCLC cells are seeded into 96-well plates at the density of 4×104 (cells/well). Then 10 µL⁄well CCK8 solution is added and incubated in dark at 37°C for another 2 h. The absorbance is determined with the wavelength of 490 nm.

Animal Administration [1]
Transient cerebral ischemia and reperfusion is prepared by BCCAO, as BCCAO is considered an ideal model to study transient cerebral ischemia and reperfusion injury-mediated inflammatory response. Mice are randomLy divided into the Sham, Model, Astragaloside IV (10 mg/kg) and Astragaloside IV (20 mg/kg) treatment groups. The Astragaloside IV treatment groups are intragastrically administered 7 days before the surgery and terminated on the day of sacrifice. On the day of the surgery, Astragaloside IV is administrated 2 h prior to ischemia. The Sham-operated and Model groups are treated with distilled water. After the mice are anesthetized with an intraperitoneal injection of chloral hydrate (350 mg/kg), the bilateral common carotid arteries are exposed and carefully separated with a small ventral neck incision and occluded twice (20 min each) with ligated surgical silk as described previously with minor modifications. There is a 10 min reperfusion period between the two occlusion periods (ischemia 20 min − reperfusion 10 min − ischemia 20 min). Sham-operated mice are subjected to the same surgical operation without the surgical silk ligation. Mouse body temperature is maintained at 37±0.5°C during the surgery with heating equipment until recovery from the anesthesia.

Astragaloside VI could activate EGFR/ERK signalling pathway to improve wound healing.
IC50 & Target[1][2]
EGFR
体外研究 (In Vitro)
Pretreatment with Astragaloside VI (AS-VI) at 1 μM increases EGFR activation in HaCaT cells. Astragaloside VI, a major intestinal metabolite of astragalosides, exerts the strongest EGFR activation. In HaCaT cells, the positive control, EGF expectedly results in 1.5±0.03-fold increase in cell proliferation, compared to the control. Astragaloside VI at the indicated concentrations also significantly promots cell proliferation in both HaCaT and HDF cells[1]. Astragaloside VI promotes neural stem cell proliferation and enhances neurological function recovery in transient cerebral ischemic injury via activating EGFR/MAPK signaling cascades[2].

体内研究 (In Vivo)
Astragaloside VI improves wound healing, compared to the control. In the simple noninfected wound model, wound healing in mice is accelerated by Astragaloside VI, where in the time required for wound closure is shortened by approximately 2-4 days, compared to that in the control group. Topical treatment with Astragaloside VI reduces the volume of pus produced, compared to the control group. Astragaloside VI treated wounds show an accelerated rate of healing, compared to the control and vaseline groups. By day 22, the Astragaloside VI -treated wounds fully close, whereas the blank and vaseline-treated wounds do not fully close until day 26. Angiogenesis is a crucial step in the formation of granulation tissue and wound healing. Astragaloside VI increases blood vessel formation in both the non-infected and infected wound models[1]. Astragaloside VI could effectively activate EGFR/MAPK signaling cascades, promote NSCs proliferation and neurogenesis in transient cerebral ischemic brains, and improve the repair of neurological functions in post-ischemic stroke rats[2].
